SPECIFICATION forming part of Letters Patent No. 413,279, dated October 22, 1889.

Application filed March 12, 1889. fierial No. 308,011. (No model.)

To (all whom it 71mg concern.-

Be it known that I, \VILLIAM HOCHHAUSEN, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improved Electric Regulator, of which the following is a specification.

My invention relates generally to the construction of electric regulators, and more particularly to that kind of regulator in which a variable resistance is employed in connection with a controlling magnet or magnets, which operate upon the controlling-lever of the variable resistance.

The objectof my invention is to provide an efficient and reliable regulator, adapted, among other things, to use in connection with dynaino-1nachines feeding lines or circuits of constant potential to which translating devices of any kind are connected in multiple.

My invention consists in various details of construction and combinations of parts in volving various portions of the regulator, such as the variable resistance, the regulating-magnet, the contact-lever of the variable resistance, the retracting devices working in opposition to the magnet or magnets, and other features, all of which will be first described in connection with the accompanying drawings, and then specified in the claims.

My invention consists, also, in a particular combination of apparatus (to be hereinafter specified) involving a dynamo-electric machine and regulating appliances for constant potential, the object of which is to obtain reliability and certainty of action, together with sinipliciiy In the accompanying drawings, Figure l is a side elevation of a regulating apparatus involving my invention. Fig. 2 is a vertical cross-section on the line X X, Fig. 1. Fig. 3 shows in side elevation a portion of the contact-plates of the variable resistance, the part of the frame holding the same being shown in section. Fig. 4: is a vertical section of one or" the spools of the controlling-magnet and a part of its sustaining plate or frame. Fig. 5 is a plan of a part of the apparatus, the supplemental retractor-lever being broken away. Fig. 6 is a diagram of circuits and apparatus, showing the manner of applying the regulator to the regulation of potential of a dynamo-machine. Fig. 7 is a part of the frame holding the contact-plates, over which the rocking contact-lever moves.

A indicates the caseof the apparatus, and A -a door of the case. The rear of the case and the door, at their upper portions B, are provided with wire-gauze instead of being solid, thus aii'ording a circulation of air to keep down the temperature of the-variable resistance mounted in the upper portion of the case at its rear. up of a series of plates or rods D, preferably consisting of ordinary sticks or pencils of -earbonsuch as are used for electric-arc lightsalthough rods or strips of other materialsuch as German silvermight be employed. The rods D are mounted between two sets of electrodes 0 C The lower set 0 consists of plates or blocks of conducting material, preferably in the form of anglepieces, one side of which is fastened in vertical position to the rear of the case, while the projecting horizontal portion has two seats or sockets to receive a pair of rods D. The upper set of electrodes, also fastened to the back of the case, is provided with pairs of springsoekets for the upper ends of the rods, for which purpose bent plate-springs O are fastened at one end to the projecting portions of the blocks C leaving iheir opposite ends tree to hold the rods in holes in such ends. The pairs of springs fastened to the same block are electrically connected through such block. The ends of the rods D, which rest in the same pairof spring-sockets, are at their opposite ends placed in sockets in adjoining blocks C; or, in other words, each pair which at their lower ends rest in the same block C at their upper ends are received in the sock ets of adjoining blocks or plates C so that the rods are connected in series through their supports. The springsoekets not only permit ready removal and replacement of rods, but also prevent breaking during transportation. Other forms of holding devices for the resistance and other kinds of resistance might be used in connection with the apparatus to be presently described; but I prefer to use those shown. v

D D, &c., indicatea series of plates of copper, brass, or other good conducting material separated from one another by thin layers of The resistance is made,

insulating material and clamped together in an opening E in a frame E by means of screws E E The bundle of plates D D is preferably Wrapped in mica or other insulator before being placedin the frame. The upper ends of the plates are tipped with platinum and form the contacts of a rocking contact-lever F, the rocking contact portion of which, at F is also faced with platinum. The opposite ends of the plates D are spread out and form means of connection for wires D fastened or connected to the blocks or electrodes 0, supporting the resistance D. The left-hand terminal blockO is connected with the lefthand terminal plate D and the same plate is also connected to one pole of the circuit in which the variations of resistance are to be produced. The other pole of the circuit connects with the rocking contact-lever through flexible copper strips E fastened at one end to a cross-piece E on the lever and at the other to brass posts E rising from the frame E. Connection with the frame and posts E is made through the supporting-post E for said frame. The obvious effect of rocking the lever F is to vary the number of rods D in circuit, the number, and hence the resistance, increasing as the point of connection changes from left to right.

The contactrlever is operated by a series or gang of eleetro-magnets, used in preference to a single magnet of the same power as the series combined, in order that there may be a greater aggregate radiating-surface, and hence less tendency to abnormal heating of the coils by the passing current. Thereby less tendency to variations of resistance exists, and derangement of the action of the regulator from this cause is, so far as may be, prevented.

The spools of the electro-magnets are indicated at G. They are hollow, are suspended separate from one another from the righthand end of frame or plate E, with a space between the head of the spools and said plate, and have their lower ends separated by an air-space from the surface beneath. These features all conduce to securing ventilating or cooling air-currents.

The cores G of the magnets are movable cores, and are attached to a common plate G preferably of ironwhich p'late carries a yoke G in turn sustained by the lever F, through a pin or screw G resting on said lever. The pin is vertically adjustable to, permit vertical adjustment of the cores G in the coils, thereby permitting their depth of immersion in the coils, or the distance of their lower ends from an iron plate, armature, or attracting mass of iron to be varied. By this adjustable suspension of the cores the initial or normal magnetic pull may be varied without disturbing the adjustment of the retractor or of other parts. The suspension of the cores from the lever is also by means of a conical bearing afforded by the conical end of the pin or screw G. This suspension of the cores permits them toaccommodate themselves to the bore of the spools in the various positions of the lever F.

It will be observed that owing to the rocking contact of lever F its fulcrum is continually changing in positiona fact which would introduce an element of complication in ad'- justing the action of retractor and magnet with relat-ionto one another if the retractor were connected to the working-lever itself, because the position of the fulcrum between the power and weight would constantly change. To get rid of this difficulty, I employ a supplemental retractor-lever H, mounted on the posts E and coupled to the lever F, or a part moving therewith, near the point of application of the pulling force, by means of a link H It is obviously necessary, in order to obtain a uniform and regular operation of the apparatus, that there should be an increase of retracting-power as near as possible in propor-' tion to the increase in magnetic pull or magnetic advantage brought about by a change in position of the magnet-cores as they are drawn into the coils. I have ascertained that this result is accomplished very well by employing a retraotor for the movable core operating after the manner of the pendulum or bent lever-balance often used as a weighing device. A pendulum-weight operating in this manner is indicated at H, and is suspended on a rod H depending from a slide or sleeve 1-1", adjustable horizontally by means of nuts on the leverH. The'weight H exerts an increasing retract-ing force as it moves from vertical position and outwardin v a direction away from the vertical line, passing through the fulcrum of lever H, and this increase is in a measure of the same degree as the increase in the pull on the cores in any new or changed position required by the conditions of regulation; hence there is a balance in all positions ready to be disturbed in all cases by any increase in the current flowing in the coils of the magnet over normal. The vertical adjustment of the weight permits an adjustment of the rate of increase of the retracting force to correspond with the rate of increase of the magnets power in changed positions of its core, or determines the sensitiveness of the device to an increase of current in the coils.

The horizontal adjustment of the weight H by sliding its support H permits the pulling and retracting power to be exactlycounterbalanced for normal conditions. Under ordinary circumstances it would be easier-to adjust the retractile force to the pulling force if the cores entered the coils but a short dis tance; but this condition weakens the power of the magnet. To overcome this objection,

I make the core extend into-the coils a considerable distance, and in order that the increase in pull or magnetic advantage maybe more nearly in accordance with the increase of retractile power of the weight, I place opbe secured.

posite the lower ends of thecore an iron plate keeper or attracting mass of iron I, which causes the cores to' pull harder with the same currents as their ends approach said plate.

A further capacity for fine adjustment is afforded by a supplemental weight H, vertically adjustable above the horizontal line of the retractordever.

K is a guide-lever for the rocking contactlever F. Lever K is pivoted in two posts K rising from plate E at a considerable distance from the rocking portion of thelever. Pivots K? extend from the rocker into the sockets at K in the guide-lever, which latter thereby holds the rocking contact-lever against horizontal and lateral displacement, while at the same time permitting it to move freely in rocking or changing its point of contact with the series of plates D". To best secure this result, the guide-lever should be horizontal when the rocking contact bears on the contact-plates at the extreme left of the series, and should be connected to the contact-lever near the extreme right of the rocking surface. when the contact rocks to the right, the points where the guide-lever and the contactlever are connected will then move together to the right, the point of connection on the guide-lever swinging down ward from the horizontal and inward toward its fulcrum on the arc of a circle, and the point of connection on the contact-lever also moving to the right as it swings with the rocking surface toward connection with the right-hand portion of the series of plates D. A dash-pot Z, connected to the lever ll, prevents violent sudden overmovement of the apparatus.

M indicates a potential indicator mounted on the base of the case, as shown, and consisting of two movable cores yoked together and moving in two fixed coils. The cores are suspended from a lever having a pendulum or bent lever retractor like that already described. Asuitable indicator or pointer moving over a scale and connected to the lever shows the volts potential.

N indicates a massive bar or rod of copper or other good conducting material fastened at opposite ends to one or more studs or rods N projecting through the case at opposite walls-as, for instance, top and bottom. The studs V project from plates or blocks N on the outside of the case, and the blocks N carry suitable clamping devices, as indicated, whereby one or more heavy conductors may By these means the principal current of the circuit to which the apparatus is connected may be caused to pass through the bar N, and a piece of steel 0, magnetized and pivoted over one face of the bar, as shown, will by such current be influenced so as to have a tendency to set itself at right angles to the bar. This influence is opposed by the superior eight of the lower end of the bar 0 and the attached pointer. By providing a suitable scale for the pointer to move over, the devices become an. ammeter or currentindicator, which may carry the whole current of a machine supplying a current of very large volume for operating a great number of devices in parallel. The device maybe readily introduced into the circuit of any machine to which the regulator is applied, by simply attaching the proper conductors to the outside plates, between which the barN is supported.

The manner of connecting up the apparatus to regulate the potential of a dynamo is shown in Fig. (5.

R indicates the dynamo having its armature connected to and supplying current to the main conductors S S, between which are incandescent lamps or other devices in multiple. The main circuit is made to include the bar N by suitable connections, as already explained.

In a derived circuit to the main conductors are placed the field-magnet coils T, the

rocking contact-lever F, an d the resistance D,

while in a separate derived circuit are placed the coils G of the magnets which act on the lever F. The coils G are of high resistance, as also are the coils T. The connections are made by attachment of wires running from one pole of the dynamo to posts or blocks 9 10, which connect within the case with the regulating apparatus in the manner indicated. The connections to the other pole may be made through a wire 12, Figs. 1 and 6, attached to one end of the bar N.

The connections within the case may be made in any desired way, the special manner or devices for the purpose being immaterial.

The apparatus having been connected as shown, and the normal number of lamps which the machine is intended to supply having been placed in circuit, the machine is started and the regulator adjusted by moving the weight 11 longitudinally until the regulator assumes position where the lamps run with the proper or desired brilliancy. 1f after cutting out lamps or other translating devices between the mains the potential remains too high, the weight ll is to be adjusted upward, the indication being that the action of the regulator'is not sensitive enough. An opposite adjustment would obviously be made for an opposite condition. \Vhen the apparatus is left to itself, a cutting out of electric lamps or other translatin device will 1 11. crease the flow of current in the branch containing magnets G, which will thereupon increase in power and pull down the regulatorlever F, causing the working contact to rock and increase the resistance in the branch with the field-magnet coils, thereby causing a decrease of current-flow in such. coils and lowering the potential. \Vhen the potential becomes normal, the magnet-cores cease to move and maintain their position, the equilibrium being maintained between the magnets pull and the retractor so long as the normal potential is maintained with the contact-lever in its new position.
